FOLDING BOX.

SPECIFICATION forming part of Letters Patent No. 367,624, dated August 2, 1887.

Application filed April 19, 1887. Serial No. 235,345.

To all whom it may concern:

Be it known that I, Co NELIUs J. HAS- BROUCK, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Folding Boxes, of which the following is a specification.

My invention relates to that class of paper boxes wherein they are cut from a sheet of pasteboard and creased properly, so that by folding said out and creased sheet or blank in a certain manner it will form a box. Such boxes may, while flat, be conveniently packed in a small compass, and they require no paste or gum in their construction.

My improved box has its bottom, back,

front, and ends all formed in one piece, the cover being, by preference, formed from a separate piece. Each end of the box is formed of three overlaid or superimposed flaps, said three flaps being attached to the bottom, back, and front, respectively, and when the box is folded a tape or string attached to the inner flap is passed through slits in the other two (outer) flaps, and these tapes are carried over the cover of the box and tied. The rectangular cover has four free marginal flaps, two of which take outside when the cover is applied to the box and two inside. The slits in the flaps for the tapes to pass through are peculiarly constructed to allow of the ready passage of the end of the tape therethrough and to clamp on the tape, so as to prevent it from slipping back.

My invention will be particularly described hereinafter, and its novel features carefully defined in the claims.

In the drawings, which serve to illustrate my invention, Figure l is a plan View of the flat blank, which is capable of being folded to form the box. Fig. 2 is a similar view of the flat blank, which may be folded to form the boxcover. Fig. 3 is a central sectional elevation of the box when set up. Fig. 4 is an isometrical perspective View of the box set up and the cover in place and tied down. Figs. 5 and 5 represent several forms of the clamping-slits in the flaps through which the tapes are passed. Fig. 6 represents a modification of this tape-clamping device, which will be hereinafter described.

(Model.)

The blank which forms the body of the box is represented in Fig. 1. This is usually cut from pasteboard or thick paper; but it might be cut from other material of a similar nature.

A represents the bottom of the box, 13 the back, and O the front. Of course either of these may be considered the front, and I simply designate them in this manner for convenience. a a are end flaps on thebottom A. b b are end flaps on the back B. c c are end flaps on the front C. The flaps at c overlap each other when the box is made or set up, and form one of the ends of same, and the flaps a b c overlap each other when the box is set up and form the other end of the box. To the flaps b and c are secured the tapes d d. In the flaps a, a, b, and c are formed clamping or clasping slits e, one in each. \Vhen the blank is folded into the form seen in Fig. 4, these slits e in the overlapping flaps (a and c, for example) coincide and they also coincide with the point on the flap (b, for example) where the tape d is attached.

The construction of the slit cispeeuliar, and it has a peculiar function to perform. If simple holes were substituted for the clampingslits c, the tapes or strings (1 would be free to play through said holes, and when the box was set up the tendency of the flaps to flatten out or resume their natural positions would not be opposed in theleast by the tapes until after the cover was placed and the tapes drawn over and tied. I so construct the slits for the tapes that the latter may be very conveniently passed through them; but a part of the material of the flap is arranged to bite on or clamp on the tape and prevent it from slipping unless considerable force is applied.

In Figs. 1 and at I have shown the slit 9 of a V form, whereby asomewhat elastic pointed tongue, 3 of the material of the flap is left free and b are next folded 'in upon flaps b and 0, respectively, and the tapes d passed through the slits e in the former by pressing out the pointed tongues formed by said slits.

The

fiaps a and a are now folded in or up and the tapes (1 passed through the slits e in thesein the same way. Now, if the three overlapping flaps forming an end he held tightly together by the thumb and finger, and the tape be drawn tight, the tongues formed at the slits e will then bite on the tape and hold all the flaps snugly together. The .said tongues may be pressed in upon the tapes by the thumb and finger, if desired, so as to make them press more forcibly on the tapes. In this condition the box will be found quite rigid and substantial, and it will retain its form under these circumstances sufficiently well for all practical purposes.

The cover D is seen in Fig. 2. It has a back flap, (1, a front flap, (l and opposite end flaps, (1 (1 These are folded along the dotted lines seen in Fig. 2, which represent the creases. The end flaps take over the outside of the box at its ends, and the back and front flaps, d d, are made a little shorter than the box and are tucked inside of the box when the cover is applied. The tapes d are then drawn over the cover and its end flaps and tied, as seen in Figs.

3 and 4..

The tucking in of the back and front flaps of the cover serves a double purpose. It serves to hold these flaps down, whereas if they were left outside they would project out in the way and effect no useful purpose, and it serves also to stiffen and brace the top of the box, and especially at the front and back.

I may form the clampingslits e in the flaps in many different ways. Some of these ways are illustrated in Figs. 5 and 5, wherein the several forms are designated by numbers. 1 represents the slit, of curved or semicircular form. 2 represents the form seen in Fig. 1, except that the point of the tongue is rounded. 3 represents the slit as forming a tongue, y, having the contour of a frustum ofa pyramid. 4 represents the slit 0 of aT shape, and 5 represents the same T form of slit, but with a portion of the flap cut away to form an aperture, 00, at the end of the slit. In all of these a tongue or tongues is or are set free by slitting the flap, and this tongue or these tongues bite on the tape when it is drawn through the slit.

In all of the figures e is designed to represent the slit, and 3/ represents the tongue or tongues freed by the forming of the slit. Except in the form of slit numbered 5, none of the material of the flap is removed informing slit 0. In passing the tape through the flap the tongue or tongues (there are two in num ber-4, for example) are pushed or pressed out to form a passage.

In Fig. 6 I show a modification in which a triangular aperture, e is formed in the flap, and a tongue, W, of sheet metal, is attached to the flap by clips. In this form the metal tongue g merely replaces the tongue y integrally formed on the flap. This would be use ful in large or heavy boxes.

In lieu of making the cover D wholly detached, I might secure its back flap, d, to the back B of the body of the box. This could be done conveniently with gum or paste. In the manufacture of small boxes I may form the cover in one piece with the box. The line of junction of the back B of the box with cover D would in that case be along the line where the back flap, d, of the cover is seen joined to the cover, the flap (2 merging into the back B. This construction is too obvious to require illustration.

It will be observed that in mybox the flaps d on the cover do not descendbelow thepoint where the tape (1 comes through, and the tape does not pass through the flap on the cover, as in some boxes of this general class. Such a construction, taken in connection with the clamping-slits 6, enables the cover to be readily removed by simply uutyin g the tapes, thetapes, when untied, still preserving the form of the box as they are clasped tightly by the tongues 1 The dotted lines in Figs. 1 and 2 represent the creases where the folds are to be made, and for convenience I have represented the inner faces of the cover and boxin these views. The tapes cl in Fig. 1 are shown attached to the flaps b and 0; but they might as well be attached to flaps 0 and c or to b and b. The contour of flaps a and a is not important. The flaps d and (I should have just the proper length to fit snugly into the box. They will then brace and stiffen it. These flaps and the flaps d are formed by cutting away the surplus material at the corners of a rectangular sheet, whereby the flaps are left free, so that two may be tucked into the box and the other two take over it outside.

Having thus described my invention, I claim 1. A folding box having overlapping flaps to one of which is attached a tape or string and the others of which are provided with slits for the passage of said tape or string,and with free tongues to clamp on said tape or string, substantially as set forth.
